The Ducks are in the North Division of the Pac-12, along with Oregon State, Cal, Stanford, Washington and Washington State. So they will play those teams every season.

The non-divisional schedule will change every other year with sites alternating. In other words, the Ducks will play at Arizona and Colorado in 2011 while playing host to Arizona State and USC; in 2012, they will travel to USC and ASU, and Arizona and Colorado will visit Eugene.

So the Ducks will play their divisional "rivals" each season. They will face each of the Arizona schools and each of the new schools (Colorado and Utah) in six of the next eight seasons. They will face each of the Los Angeles schools in four of the next eight seasons.

Here's the Pac-10/12 release, and here's the entire Pac-12 schedule for 2011:
